The primary purpose of my invention is for the operating of pumping units of the reciprocating piston type.

A further object of my invention consists in providing a driven shaft and having a.

pinion mounted upon the driven shaft and having one or more internal gears adapted to be actuated through the coacting of, the

pinion with each of the internal gears to impart a reciprocating motion to thepiston rods secured to the internal gear elements. A housing and guideways are provided for the gear elements and journals are provided in the housing for the rotation of the driven shaft therein. The housing is slit to provide for the maintenance, placement and adjustment of the internal driven gears that are disposed within the housing. Means are also provided, at the end of each stroke of the internal gear, to move the same laterally as the pinion is transferred from one side of the internal gear to the other.

The main object of my invention is to transform rotary movement to reciprocating movement through coacting gears. V

'A further object of my invention consists in having a common driving pinion, for one or more internal driven gears, in order that the gears may be manipulated in opposite directions simultaneously V the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set so taken on line 3 ofFigQQ looking inthe direction indicated, l
